Description Andrew Alm 2007-08-07 18:07:38 EDT
This relatively new motherboard causes the kernel to hang at bootup unless you
specific pci=nommconf as a kernel parameter.  If I understand correctly there is
a blacklist for motherboards that have this behavior so I think it just needs to
be added to that.  Ive included the output from dmidecode, will that be enough
to get this on the blacklist?

I tried the latest BIOS update and it does not resolve this is issue either.
Comment 4 Andrew Alm 2007-09-14 07:33:17 EDT
Any update on this?  The bug is also appearing in F8 Test 2 Live CD.

I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the fedora kernel.


This bug appears to have already been flagged by the kernel developers for
blacklisting however I will add an F8 blocker bug as well as it is preventing a
successful initial install.

Thanks for filing.

Not a release blocker, pci=nommconf allows installation.
Comment 7 Christopher Brown 2008-01-10 15:17:36 EST
MMconfig was disabled in Fedora 7 & 8 release so closing this as the install
should have proceeded without issue for Fedora 8 final. Thank you for filing the
